ABSTRACT:
A magnetic transfer method which superposes on a magnetic disk surface a magnetic transfer master disk (2) on which a magnetic film is formed so as to have an array pattern shape corresponding to a preset information signal, and magnetizes the magnetic film on the master disk (2) to thereby magnetic-transfer-record the array pattern of the information signal on the master disk (2) onto the magnetic disk as the magnetized pattern of the information signal, the method characterized by comprising a step of contacting/separating to/from a dummy disk (1) the magnetic film-formed surface of the master disk (2) to thereby clean the master disk (2), and a step of superposing, after the cleaning, the master disk (2) on the magnetic disk for magnetic transfer recording; and a magnetic transfer device for the method.
